A 64-year-old woman slipped on an icy walk, falling forward and striking her forehead. She had a brief convulsion immediately after the fall, was unresponsive for less than 1 minute, and awakened with a severe generalized headache and nausea but no vomiting. In addition to being perplexed about the circumstances of the fall, she could not recall the previous few hours. She was awake and oriented and had no abnormalities on neurologic examination. Tenderness and a scalp contusion were apparent at the site of the impact, and there were abrasions on her right cheek. What is the expected course, and how should her case be managed?

I've had symptons similar to a mild concussion, eg, feeling of dizziness, headache, pressure in skull. But I didn't have any blow or shock to the head to cause it. Any one heard of this? Can you have a mild concussion without a shock to the head, ie something produced by internal strsses in the skull or brain ?
